physicsThis is my full work... First I had to find the capacitance so, C=[(8.85*10^-12)(.04)^2]/.0005 =2.832*10^-11 F =28.32 pF Now I have to find the charge on the positive electrode, so i tried Q=CV =(28*10^-12)(300V) =8.0*10^-9 but it's wrong

physicsyes! that's exactly what I thought. So i ended up figuring that out and got 2.8*10^-9 coulombs but somehow it's still wrong
